Hooking up UART to Microcontroller

[digi001]

Can anyone suggest any good design examples (schematic ) for a UART to Microcontroller design? Preferably a Motorola Type MCU and a Advanced Multi-Channel UART with FIFO.

Without selecting a particular processor and UART a schematic would be very general.

The best way to run a UART is hardware interrupt driven with a FIFO buffer in the UART driver software for background servicing for the operating systems. The FIFO in the UART is primarily to provide a small reserve bucket to account for operating system delay in servicing the hardware interrupt. The driver buffer is a first in, first out que with input and output pointers. Multi-channels would just be multiple driver ques just as if there where physically different UART chips.

OK thanks!

The Quad UART I am looking to use is #sc16c754b.

Rather than use a Software buffer I plan to use the built in FIFO in this advanced UART chip.
